WITHIN THE SPACE OF THREE MONTHS, IN THE MIDDLE OF DRIVING MY SMARTCAR, MY DASH DISPLAY HAS GONE FROM SHOWING D (FOR DRIVE) TO N AND THEN FLASHING THREE VERTICAL BARS. I HAVE LOST ALL CONTROL OF DRIVING THE CAR AND LUCKILY THERE WAS SPACE ON THE SIDE OF THE ROAD TO COAST TO A STOP. WHEN TRYING TO TURN THE CAR BACK ON, THE THREE BARS REMAIN. THERE IS A WAY THROUGH THE SHIFTER TO RESTART THE CAR OR AT LEAST GETTING IT INTO NEUTRAL. A SERIES OF PUMPING THE BRAKE, TURNING THE START KEY AND TRYING TO MOVE THE SHIFTER BACK AND FORTH THROUGH GEARS. EVENTUALLY, THE CAR WILL START. UNFORTUNATELY, THE THREE BARS OF DEATH (AS NICKNAMED ON THE SMART CAR FORUMS) CAN HAPPEN FOR ANY NUMEROUS TYPES OF FAULTS SUCH AS WEAK BATTERY TO FAULTY COMMUNICATION WITH THE TRANSMISSION, TO HEATER/AIR CONDITIONING OPERATING UNIT IS DEFECTIVE. THE LIST IS LONG. THE PROBLEM IS MY CAR HAS COMPLETELY STOPPED WORKING IN THE MIDDLE OF THE ROAD WITHOUT WARNING AND THIS COULD BE VERY DANGEROUS. *TR

I AM ORIGINAL OWNER SINCE FEB 09 (MANF 12/08) AND ITS NOW 7 YRS OLD AND REQS NEW BATTERY. LIFTING UP FLOOR MAT TO REMOVE OLD BATTERY I NOTICED STICKY RED OILY SUBSTANCE (UNKOWN SOURCE BUT NOW SUSPECT BATTERY VAPOR CONDENSATION) AROUND TOP OF COMPARTMENT (MOSTLY WHERE HOLDDOWN BRACKET CONNECTS). REMOVING THE BATTERY THEN EXPOSED CORRODED FLOOR PAINT FROM BATTERY ACID. IN ATTEMPTING TO CLEAN UP THE MESS, I HAD TO REMOVE THE BATTERY VENT TUBE EXITING THE FLOOR. THIS TUBE HAD A SPIDER NEST INSIDE ABOUT 2" FROM OPENING. WD40 DID NOT PENETRATE NESTS END SEALS & HAD TO EXTRACT SPIDER & NEST MANUALLY. I CAN NOT PROVE THIS IS SAFETY RELATED BUT IM WONDERING IF OTHER VENTED BATTERY CARS HAVE THIS VENT BLOCKAGE-CORROSION PROBLEM AND ALSO IF THESE BLOCKED FUMES WERE TOXIC TO OCCUPANTS OF MY CAR? I TOOK SOME PHONE PHOTO EVIDENCE. ON UNRELATED PROBLEM. IN THE LAST 1-2 YEARS I ALSO HAVE THE PEELING TOP CLEARCOAT PROBLEM REPORTED BY OTHER OWNERS OF 2009 RED PAINT (NON METALIC) WHICH IS PRIMARILY ON HOOD PANEL & OTHER TOP SURFACES EXPOSED TO DIRECT SUN WHICH LEAVES THE DULL RED BASE COLOR OF THE PLASTIC PANELS.

CAR HAS JUST OVER 17K MILES ON IT. THANKFULLY I WASN'T IN HEAVY TRAFFIC AS THIS COULD HAVE CAUSED AN ACCIDENT BY SOMEONE REAR-ENDING ME BECAUSE OF THE REDUCED SPEED AND STALL. I HAD TO HAVE SOMEONE PUSH ME UP TO A PARKING LOT WHILE I WAITED FOR A TOW TRUCK. A MONTH LATER I AM STILL WAITING ON A REPLACEMENT FUEL PUMP. THE ORIGINAL BOSCH KEEPS BLOWING FUSES AND STALLING OUT. MY MECHANIC TEST DROVE IT AND HE HAD TO BE TOWED BACK TO HIS SHOP AS WELL BECAUSE OF A STALL/BLOWN FUSE BECAUSE OF THE FUEL PUMP ISSUE. THESE FUEL PUMPS SEEM TO BE ON BACK ORDER BECAUSE LOTS OF SMART CARS ARE HAVING THE SAME ISSUE AT THE MOMENT WITH THEIR BOSCH FUEL PUMPS.

EA17003 · Engine Compartment Fire

Opened Sep 1, 2017 · Closed Aug 21, 2018

Status: closed (inferred from source dates) · Engine

On April 30, 2018, Mercedes-Benz USA, LLC, (Mercedes-Benz) submitted a Defect Information Report (DIR) to NHTSA regarding a defect that could result in a vehicle fire starting from the engine compartment in 42,781 model year (MY) 2008 and 2009 Smart Fortwo cabrio and coupe vehicles (451 platform).According to Mercedes-Benz?s DIR, ?the rear insulation mat within the engine compartment might deform, deteriorate, loosen and over time, subsequently be able to contact hot components of the exhaust system.This could lead to an ignition of the insulation mat and possible fire in the engine compartment.?The US-specification exhaust system has an external catalytic converter packaged close to the insulation mat, where temperatures in the vicinity of the insulation mat reach high values.Over time, these temperatures can lead to a change in the insulation mat's material characteristics and ultimately allow the material to deform. Depending on the magnitude and the specific location of the deformation, the insulation mat could contact hot components of the exhaust system and ignite.Mercedes-Benz will replace the rear insulation mat on the affected vehicles with the improved mat first implemented in the United States in MY 2010 vehicles.ODI?s analysis of fire incident field data reported to NHTSA and Mercedes-Benz show an increasing trend of non-crash fires in the subject vehicles that begins after 4 years of service and accelerates after 7 years of service.The analysis shows that this trend is driven by fires occurring in the engine compartment.Forensic investigations of fires occurring in the past year identified the insulation mat as a likely or possible cause of most of the fires originating in the engine compartment.This investigation is closed based on Mercedes-Benz insulation mat recall.For more information about field data trends and fire investigations, see the closing resume in the document file for this investigation.

Status: closed (inferred from source dates) · Engine

On December 16, 2016, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE16-016 to investigate eight complaints alleging incidents of engine compartment fire while driving or shortly after engine shutdown in model year (MY) 2008 through 2009 Smart Fortwo vehicles.The complaints appeared to indicate an increasing trend, with all eight fires occurring since January 2015.As part of PE16-016, ODI analyzed information related to incidents reported to the Office by consumers, analyzed field data and technical information submitted by Mercedes-Benz USA (Mercedes) in response to the PE16-016 information request letter, and analyzed non-crash vehicle fire claim data provided by the Highway Loss Data Institute (HLDI).To date, ODI's analysis of incidents reported by consumers and provided by Mercedes has identified 27 incidents of open flame fires originating in the engine compartments of the subject vehicles, 14 of which were reported to ODI by Vehicle Owner Questionnaires (VOQs) and 18 involving complaints or field reports to Mercedes (5 of the incidents were reported to both ODI and Mercedes).One incident reported to Mercedes includes an allegation of an injury from smoke inhalation.Nineteen (19) of the incidents occurred since January 2015.Mercedes has only investigated 2 of the 27 fire incidents, and the company was unable to identify a vehicle-based cause for either incident.To further assess incident rates and trends, ODI requested fire claim data for the subject vehicles and eight peer vehicles from the Highway Loss Data Institute (HLDI).HLDI collects insurance claim data from companies representing over 80 percent of the market for private passenger vehicle insurance in the United States.ODI?s analysis of the HLDI data, which covered the period from 2010 through late-2016, found that the MY 2008 Fortwo vehicles had a significantly higher claim frequency than its peers and, similar to ODI?s complaint trend, experienced a sharp increase in claims in 2015.This investigation has been upgraded to an Engineering Analysis (EA17-003) to continue to investigate the high frequency and increasing trend of non-crash engine compartment fire incidents in the subject vehicles.The VOQs associated with the opening of this investigation were:10676359, 10780222, 10790017, 10820891, 10872656, 10944676, 10916505, 10924311, 10924637, 10939504, 10945296, 10993895, 11011100, 11011565.
